About This Site

This site was created by lion biologists in Africa who realized the importance of lion age for management, research, conservation and sustainable hunting. The resources available here were developed using decades of scientific research on lion biology. We invite you to use this site to improve your aging skills and extend a friendly challenge to boost your aging accuracy score to 100%!

Why Age Lions?

Age is a common metric used throughout the world to guide the management, research and sustainable hunting of many types of wildlife, including large carnivores, ungulates and fish. Knowing an animal's age is critical for accurately estimating key elements of wildlife behavior and life history, such as reproduction, survival, movement and population size. Our ability to successfully conserve and manage wildlife depends on how well we understand each animal's social and biological role, which is closely tied to age.
